Abstract: ABSTRACT      A method and apparatus for forming piston rings are disclosed, A split piston ring made by conventional processes is locally heated along its inside surface for a short distance either side of the split.  This causes a short length of the ring on either side of the split to curl into a slight inward protrusion due to internal yielding of the restrained heated area and subsequent tensioning during cooling.          The inwardly curved configuration prevents catching of the ring's ends on valve ports of ported cylinder engines.

Abstract: ABSTRACT OF THE DISCLOSURE Objects on a delivery conveyor are detected by a photo-detector connected to a multi-bit shift register which is clocked by a pulse generator connected to the delivery conveyor. A NOR gate is connected between two outputs of the shift register and the shift register resets to erase information relating to undersized objects. Another circuit having NAND gates connected to a series of shift register outputs and to a counter connected to the pulse generator determines the presence of objects over a base size. A comparator connected to the counter provides a signal to a microprocessor, connected to the shift register resets, to erase information relating to an oversize object. Another section connected to the intermediate output of the shift register detects the location and length of gaps between adjacent objects. This section provides information to the microprocessor which through its connections to the shift register erases information relating to the leading object if the gap is too small. Signals leaving the shift register enter a second shift register and are monitored at variable output points by the microprocessor. A detector adjacent to a receiving conveyor detects sections to be loaded. A circuit connected to this detector and a pulse generator connected to the receiving conveyor generate signals fed into a multi-bit shift register also having outputs connected to the microprocessor. The microprocessor determines the alignment of an object and a receiving position and turns on an air jet to effect a transfer.

Abstract: ANSTRACT OF THE DISCLOSURE      A chain has alternately arranged center links and sidebars that are interconnected by pins of a predeter-mined diameter.  An elongated opening is provided in each center link for receiving two pins.  Adjacent each end of the elongated opening, lugs project from the center link to restrict the opening opposite the lug, to a transverse dimension less than the pin diameter.  Each lug is spaced from an adjacent opening end by a distance enabling one pin to fit between the adjacent opening end and the lug.  Each pin has a transverse groove for receiving one of the lugs when the pin is in a predetermined rotational angular relationship with the center link.  Thus, the pins can be moved past the lugs, in directions to and from the adja-cent ends of the  elongated openings, when the pins are in the predetermined rotational angular relationship for assembly or disassembly of the chain.  The lugs prevent collapsing of the chain when the predetermined rotational angular relationship is not maintained.                               -1a-

Abstract: Abstract A log centering apparatus and method are described employing an optical log scanner for determining the longi-tudinal axis of the log for optimum wood product production by transmitting light to detectors through the space between the side of such log and reference edge members.   The de-tectors each include a linear array of photosensitive diode-which are electronically scanned to take a reading.  Before scanning, rough centering arms clasp the log and its opposite ends are engaged by rotation spindles.   The log may be ro-tated intermittently or continuously during scanning to measure at different angles the distance between the reference edge and the surface of the log at a plurality of points spaced longitudinally along the log.  These distance signals are fed to an electronic computer to compute the optimum yeld axis of such log.  The spindles on which the log is rotated are moved horizontally and verically after deter-mination of its optimum axis, to reposition the log until such optimum axis is in alignment with a reference axis, spaced a predetermined distance from a work axis, such as the lathe of a veneer lather.  The preferred embodiment of the invention is a veneer lathe charger.  After repositioning the log in alignment with the reference axis, such log is reclamped and held while the spindles are removed ? that the ends of the logs can be engaged by pivoted pendulum-like transfer arms which transfer the log from such reference axis to alignment with the lathe axis.
